Surface water means the system draws its water from rivers, lakes, streams or reservoirs. 61 Minnesota systems (0.9%) list surface water as their primary source.

Does Grand Portage have drinking water violations?
Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in February 2026. The violations listed here began between August 2024 and February 2026. By type: 6 public notice, recordkeeping or other, 5 monitoring and reporting and 1 monitoring. The contaminant or rule involved most often is Public Notice (6 of them). EPA lists 11 as resolved and 1 as archived. Resolved means at least one resolving action is on record: the system returned to compliance, the rule no longer applies, or no further action was needed. Archived means the violation was not marked resolved but is more than five years past the end of the noncompliance period, so it no longer counts toward current compliance status.
